Product Description
Urea, an organic compound composed of carbon, nitrogen, oxygen and hydrogen, is a white crystal. One of the simplest organic compounds, it is the main nitrogenous end product of protein metabolic breakdown in mammals and some fish.As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to preserve, easy to use, small damage to the soil, is a large use of a chemical nitrogen fertilizer, is also the highest nitrogen content.
